thingiverse

Pinhole glasses. If you have never heard about them, they are a device used in medical field to train your eyes, especially nowadays that we spend lot of time in front of a screen. I won't be listing the benefits, but here you can have a look: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5383620/ The ones posted here have no medical approval, but I replicated the same dimensions reported in researched and commercial ones. Hole size has to be between 0.9 - 1.2mm Hole distancing has to be 2 - 3mm Pattern on lenses shall be regular and perfectly symmetrical. I will be investigating more about some studies about them. Meanwhile: - Be sure you print them with the lenses on the print bed. This will guarantee a perfect regular hole shape. - Be sure you fine tune your printer (flow rate, horizontal expansion, holes compensation) cause the precision of the holes is essential and is the main point of this device. I will be posting soon the articulate version (have a look at my original glass frame https://www.thingiverse.com/thing:4361937). If you want a pair like this with different shape or a different size or hole spacing, contact me. Be sure you read the usage guidelines before using them and do it at your own risk.
